A movie theatre in Austin, Texas got a free anti-texting-and-talking ad when a kicked-out customer left them an angry voicemail.

The Alamo Drafthouse said in a recent blog post that it booted a texting movie-goer when she continued texting despite two requests to stop. The angry customer, who was removed from the theatre without a refund, then left an angry voicemail.

The voicemail (video below) is now played before the Alamo’s R-rated movies as a warning to all the customers to think twice before texting.

The cinema has had a no-talking-or-cellphone-use policy since 1997, explaining “if you can’t change your behavior and be quiet (or unilluminated) during a movie, then we don’t want you at our venue.”
